Dry eye syndrome is a very common condition with multiple etiologies that includes systemic and ocular disease that causes reduction in the production of tears, as well as increase in tears evaporation. As a result of the various etiologies and large variability of dry eye's clinical sign, it has been a challenge for practitioners to have a consistent system to classify dry eyes and to have an appropriate and accurate measurement to quantify the severity of dry eyes and its impact on patients' quality of life.6 To date, no study which evaluates the extent of questionnaires correlates with changes in quality of life. With this cross sectional interview study, we aim to determine the efficacy of the questionnaires as a practical tool in our future clinical trials at our center.
